My first knowledge of this really handsome plant was from 
specimens which flowered at Sion House in 1845, raised from 
seeds sent to his Grace the late Duke of Northumberland by 
Dr. Wallich, but from what country is not known. The deter- 
mination of the species of Datura is attended with great diffi- 
culty, as all will acknowledge who have made the attempt, 
partly owing to very imperfect specimens in our herbaria, and 
more so from the very variable character of the individuals, their 
change of colour, and their disposition to become double ; and I 
confess myself to have been fairly puzzled with this, and I put 
the drawing of it aside for future consideration. = 
In May of the present year my attention was again directed . 
the subject by a recent specimen of the same plant, sent by the 
Messrs, Henderson, of the Nursery, Pine-apple Place, ee 
Road, who received secds of it from Mr. Francis, the curator 0 
the Adelaide Botanic Gardens, South Australia, with the fol- 
lowing remarks :—* A species of double yellow Datura, very 
Plentiful in these parts, sweet-scented, and flowering all the 
summer, of a low spreading habit, producing its flowers ee 
to eight months throughout the twelve. This will be a use
